Induction surface hardening is a widely used manufacturing process in order to improve the mechanical properties of components. However, better process understanding as well as process development requires numerical modeling. The modeling itself depends on the input data regarding the process and the material behavior. Data acquisition is a rather difficult task due to very short process times, as seen in contour hardening of gears. The paper will give an overview over critical aspects regarding input data and their acquisitions as well as a comparison between experiments and simulation in order give a better understanding for improving the modeling.
